What should the students do to produce more precise data regarding the speeds of the methods used?

• Conduct the study for 3 more days.

• Take a different route home in the evening.

• Switch the method used to get to school in the afternoon.

• Use a different timer in the afternoon than in the morning.

Student 3 and Student 4 noticed that they had the same average time. The students want to do a second investigation to determine who is faster. How can the students best determine who is faster during the second investigation?

• The students should switch methods. Student 3 should skateboard and Student 4 should roller skate.

• Both students should use the same method they used for the first investigation.

• The students should take turns using the same method. Student 3 should use the skateboard first and then Student 4 should use the skateboard.

• The students should do only half of the investigation. Student 3 should be timed going to school and Student 4 should be timed going back.

For the second investigation, Student 2 decided to use a bike instead of a kick scooter. She was able to obtain an average time of 4 minutes. Which describes Student 1's first investigation and Student 2's second investigation?

• Student 2 created a larger unbalanced force than Student 1, resulting in a slower speed and longer time.

• Student 2 created a larger unbalanced force than Student 1, resulting in a faster speed and shorter time.

• Student 2 created a smaller unbalanced force than Student 1, resulting in a slower speed and longer time.

• Student 2 created a smaller unbalanced force than Student 1, resulting in a faster speed and shorter time.

The student wants to use a scooter to go to school. She cannot decide whether to use an electric or gas powered scooter. Electric scooters use a battery that can be charged overnight and used the next day. Gas powered scooters burn gasoline and release fumes in the air the ways cars and trucks do. Her school is an environmentally friendly campus. Which would be the better choice to keep her in agreement with the school values?

• Use an electric because it's quiet.

• Use an electric because it reduces pollution.

• Use a gas powered because it is faster.

• Use a gas powered because it is more widely used.
